Enable file logging ( True , "Debug.Log" , False ); // Remove the silent keyword logger.RemoveSilentKeyword( "Password" ); // Log a message after removing the keyword from the silent list Logger.Log(info, "User entered password: 1234" ); // Add keyword filter logger logger.AddFilterKeyword( "success" ); // Log a message that will be filtered out logger.log(info, "Operation failed" ); // Log a message that will pass the filter logger.log(info, "operation successful" ); // Remove the keyword from the filter logger.RemoveFilterKeyword( "success" ); // Use the general Log function for initialization logging.initialize(warn, true , "warning.log" , true , TIME_SECONDS , true , false , true , true ); // Use the general Log function to record warning logs (warning, "This is a warning message" );
